1.3x - 10= 0.8x - 8
solve for x

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

Add 10 to both sides.

1.3x = 0.8x + 2

Subtract 0.8x from both sides.

0.5x = 2

Divide by 0.5.

x = 4.

Proof:

1.3x - 10 = 0.8x - 8

1.3(4) - 10 = 0.8(4) - 8

5.2 - 10 = 3.2 - 8

-4.8 = -4.8

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

start by getting all like terms to the same side

subtract 0.8 x from both sides, add 10 to both sides

0.5x = 2

divide both sides by 0.5

x = 4

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
